1 Claim.

through the shaft on which the block is mounted and by which it isrotated. 1

In order to give an understanding of the invention, I have illustratedin the drawing a selected embodiment thereof which will now bedescribed, .after which the novel features will be pointed out inthe-appended claim.

In the drawing:

The single figure is a vertical sectional view.

through a'wire-drawing block embodying my invention.

In the drawing, 1 indicates the wire-drawing block which is formed withthe usual wire-receiving surface 2 on which the wire 3 is wound after ithasbeen drawn through the die 4. This block I is mounted on and isrotated by a suitable driving shaft 5 which may be operated in any 35provided with an open-topped lubricant-containing 9 adapted to receivedry lubricant for lubricating the wire and the wire-receiving sur- 1face ofthe It indicates a stationary plow element located within thechamber 9 and acting member 8 is rotating. 4 I v 1 The-lubricantcarrying member 8 is shown. as mounted on a sleeve l'l through which theshaft 5 extends, said sleeve being journaled in the frame 5 notthewire-drawing machine. 1

4 Means are provided for driving the sleeve H at aslowerrate than thatat whichthe drum] is driven, and for this purpose, said sleeve isprovided with a gear I! which meshes with and is so driven by a drivinggear I4. 'Ihe construction and operation of the lubricantcontaining'member 8 with aslow moving rotatable dry lubricant carto plowthe dry lubricant against the drum as the 1939, Serial No. 287,711

is similar to that illustrated in my co-pending application, Serial No.23

The block I is rovided with an interior chamber l5 and means areprovided for.cooling the block by introducing water into the chamber"through the shaft 5, and delivering the water against the walls I6 ofthe chamber l5.

For this purpose the shaft 5 is a tubular shaft and there is provided awater supply pipe I! which extends through the bore I8 of said shaft 5.This supply pipe is stationary and is cononected to any suitable sourceof water supply. Said pipe at its upper (and leads into a hollow headmember I9 which is provided with one or more laterally extending spraypipes 28 that are con- 1 structed to deliver jets of water against theinterior wall l6 of the block.

In the operation of the device, the water supply pipe H and the nozzlepipes 20 serve to deliver water or other cooling liquid against the'wall l6 of the drum as the latter is rotated, thereby keeping thewire-receiving surface of the drum cool. The supply pipe I] is somewhatsmaller than the bore l8 of the tubular shaft Sand the space between thepipe and the, shaft provides 25 a drain outlet through which the watermay drain, after ithas performed its cooling function.

The block I is shown as having a removable cap piece 2| which normallycloses the upper end be readily removed whenever it is necessary toobtain access to the head l9 and spray pipes 20. I claim; A, Awire-drawing machine comprising a chambered wire-drawing block, avertical tubular shaft u on which the block is mounted and by which itis rotated, a water supply pipe extending axially through said shaft andinto the chamber of the v block, a hollow head secured to said pipe andlocated within said chamber .and into which the pipe delivers water forcooling the drum, and a plurality of spray pipes extending radially fromsaid head member and arranged to deliver said water against the walls ofthe chamber in the block at a plurality of points circumferentiallythereof, the supply pipe being smaller thanthe interior diameter of thetubular shaft, thereby providing. a passage for water to drain out thechamber through said shaft. v a I enemas n.
